Sometimes I have these really bad panic attacks for no reason and I think completely irrationally and start to freak out . For instance last night I took 3 advil PM's to get to sleep which was only one pill over the recommended dose . Then as I was trying to fall asleep my throat felt all weird and I became positive it was because it was closing up and I was going to suffocate in my sleep . My heart started pounding and the more I thought about it the surer I was and I started pacing like mad .

Why did I take 3 advil PM's to get to sleep ?
